'I Am the Lord' in the Bible

Because all the first-born are mine; for on the day that I smote all the first-born in the land of Egypt, I hallowed to me all the first-born in Israel, both man and beast: mine they shall be: I am the LORD.

And thou shalt take the Levites for me (I am the LORD) instead of all the first-born among the children of Israel; and the cattle of the Levites, instead of all the firstlings among the cattle of the children of Israel.

Take the Levites instead of all the first-born among the children of Israel, and the cattle of the Levites instead of their cattle; and the Levites shall be mine: I am the LORD.

Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with the trumpets over your burnt-offerings, and over the sacrifices of your peace-offerings; that they may be to you for a memorial before your God: I am the LORD your God.

I am the LORD your God, who brought you out of the land of Egypt, to be your God: I am the LORD your God.
